Subject: [PATCH 00/79] fs: new accessors for inode->i_ctime
Date: Wed, 21 Jun 2023 10:45:05 -0400 [thread overview]
Message-ID: <20230621144507.55591-1-jlayton@kernel.org> (raw)
I've been working on a patchset to change how the inode->i_ctime is
accessed in order to give us conditional, high-res timestamps for the
ctime and mtime. struct timespec64 has unused bits in it that we can use
to implement this. In order to do that however, we need to wrap all
accesses of inode->i_ctime to ensure that bits used as flags are
appropriately handled.
This patchset first adds some new inode_ctime_* accessor functions. It
then converts all in-tree accesses of inode->i_ctime to use those new
functions and then renames the i_ctime field to __i_ctime to help ensure
that use of the accessors.
Most of this conversion was done via coccinelle, with a few of the more
non-standard accesses done by hand. There should be no behavioral
changes with this set. That will come later, as we convert individual
filesystems to use multigrain timestamps.
Some of these patches depend on the set I sent recently to add missing
ctime updates in various subsystems:
https://lore.kernel.org/linux-fsdevel/20230612104524.17058-1-jlayton@kernel.org/T/#m25399f903cc9526e46b2e0f5a35713c80b52fde9
Since this patchset is so large, I'm only going to send individual
conversion patches to the appropriate maintainers. Please send
Acked-by's or Reviewed-by's if you can. The intent is to merge these as
a set (probably in v6.6). Let me know if that causes conflicts though,
and we can work it out.
This is based on top of linux-next as of yesterday.
